I use electric, I'd like like to build a coal smoke house.
That being said I've got a master built up right smoker. My only complaint was it didn't seem to put out enough smoke, so I added a smoke daddy smoke attachment. There are a few other minor details I don't like but it's nothing major nothing that would not make me buy another, actually bought one for my dad this year for Father's Day
When you buy your smoker buy one of these too, smoking isn't really a put it in at 250 for 3 hours thing it's more of a put in at 250 and it's done when your meat hits 165
